DE'INATING DEVICE.

Specification of Letters Patent.

Patented J an. "4', 1.919

Application filed August 12, 191B. Serial No. 249,533.

To all whom t may concern:

Be it known that I, Louis It. Non'riuu, a citizen of Belgium, and a resident of the borough of Brooklyn, in the county of Kings,

city and State of New York, have invented certain new l and useful Improvements in Detonating Devices, of which the following is a specification. y

This invention relates to detonating devices 0f minor order, `and `appertains more especially to improvements in that class of articles which are known under the names of cracker bon-bons and snapper favors.

It is fainiliarly known that` the so-called favors and bon-bons above referred to are usually made up into small packages containing a gift, prize, or confection of Sonie sort, surrounded by a casing of light card board, to which a fuse and an explosive are attached, the whole being wrapped in tissue paper folded so as to let the fuse protrude outward, either alone or with an additional strip of paper used for a counterpart. Both of the latter must be of the same width so that they will lie closely one upon the other within a tight fitting wrapper incr-der to produce a satisfactory detonating effect. The wrapping of the strips has to be carefully done by hand and is therefore necessarily expensive. A further defect found l in the means hitherto adopted for effecting the detonation of the explosive, which are generally inadequate for the purpose in view.

@ne of the objects of the present invention is to produce an improved device of the character described enabling the favor or other article to be exclusively held within the casing provided therefor, and the detonator to be carried by the latter on its outer surface. A

Another object is the production of a device of the nature set forth furnished with wedging means adapted to be passed through a relatively constricted channel, whereby the explosive or detonating substance shall be set off positively in an unfailing manner.

it further object is to provide a device of the class mentioned capable Ofbeing positively anchored to a container for a favor or the like by the saine means as are eniployed for maintaining the effective constituent parts of the device' operatively together.

Still another object is the provision of a ydevice ofthe type specified which shall be simple in construction, composed of few parts that do not require tight fitting nor careful wrapping, and susceptible of being expeditiously assembled by low-priced and comparatively inexperienced labor.

Other objects and advantages of the in vention will become apparent as the specification proceeds. y y

With the aforesaid objects in view, the invention consists of the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated on the annexed drawing, wherein like parts are designated by the same reference characters throughout the` several views.

In the said drawing:m

Fig. XI is a perspective view of a similar article furnished with a plurality of detonators.` l

In these views the reference numeral denotes a relatively fixed member; which as viewed in Figs. I and II occupies the lowerniost position. This member may have any desirable form; for instance, it may constitute the side wall of a `Casing' wherein is vbe reversed, if desired. l v portion ofthe staple 3 lsmadessemi-yielding deposited the favor usually dispensed at certain social functions. u K K At a slight distance above the said meniber l, is placed an auxiliary or protective member 2, likewise relatively fixed, but of the bottom member l, and serve to' hold they top niember 2, thereoven as clearly representedinfFig. IIL

Between the two said members land 2, is a movable element' 4,- preferably disposed parallel therewith. As shown, the element 4 may be held upwardly in contact with the top member, and' itis arranged toslidefbetween the same andthe bottom member when pulled outwardly with relation to a. favor or its container.

An ignitible compound 5 is carried at thc under side of the aforesaid movable element Ll, the same projecting downwardly therefrom in close proximity tothe surface of the bottom member previously mentioned. As Fig. lII shows, the Vcompound 5 may be appliedto the'inne'r extremity of the element i, and made to fill, or approximately so, gap or vacant space intervening between the latter and the bottom member.

Across the upper fare of the bottom member l, and substantially in alincment with the staple 3'," above described, isl laid a detonating composition 6, which is caused to adhere to the said face of the member. It will be observed, by referring to Fig. Il, that the composition 6 about fills the same space or gap as the before mentioned,compound 5, and together the compound and composition co-act in maintaining the movable element l in substantial parallelism with the relatively fixed members l and 2, whether applied in thin layers or in thick strata in the manner illustrated. Y

An enlargement 7 which may be produced in any appropriate manner, is formed on the upper face of the movable element et, directly over the compound 5, applied Ito the opposite side. Due to its peculiar location, 'this enlargement is adapted to exert a wedging action against the under side 'of the 'top member 2, when drawn past the latter, and will thereby cause sufficient friction between the compound 5 and composition 6 to effect the contemplated dctonation, as they are forced one against the other. lThe relative positions of these elements, substances, or ingredients 5 and 6, it will be noted, may well The intermediate 'in order 'that the enlargement 7 may pass thereunder without risk of tearing or otherwise injuring the movable member.

The variant form of the invention exemplified yin Figs. III and IV comprises the same combination and arrangement of parts as appertain to the two preceding views, with the exception of the stationary meinber 2, which is omitted. The several parts of this variant form are therefore numbered similarly to those before described, with the addition of the exponent letter a The top member aforesaid being absent, it will be perceived that the wcdging action of the enlargement 7a of the movable element l. is effected directly against the under side of the middle portion of the staple 3a. The detonation is produced upon impact of the compound 5l and composition 6, respectively carried by the inner end of the clement l, at the under side thereof, and by the relatively fixed member la, on the latters surface.

In that other variant form of the invention represented by Figs. V, VI and VH,-

the staple 3b is inverted, and the turned over extremities thereof serve as a pair of guides for the movable element 4" over the stationar 7 member l". The enlargement 7" in this form of the invention is produced by folding over the inner end of the element 4l). lt is forced against and between the said extremities of the staple, which are oppositely disposed and set closely adjoining each other, as illustrated. The friction occurring bctween the compound 5l and composition 6" here again causes the detonation.

It will be understood that the said ignitible compound and the said detonating com` position may be mixed together, instead of being separate as hereinbeforc described, in which event the one mixture is worked with a companion surface made up of some abrasive material, substituted for the missing part. A construction embodving this feature is illustrated in Figs. VIII and IX, where an abrasive surface is incorporated with the under side of the staple 3". Such a. surface is conveniently produced by corrugating the under side of the middle portion of the staple, as shown. The (o-acting ignitible and detonating ingredients may in that case be placed together in one mass or body, as at 7, by the side of thc said abrasive surfare, while the parts 5C and 6c will merely constitute enlargements of the movable element 4C and stationary member l, respectively. Or else, both of the parts 5C and 6C may be detonators, and 7c an igniter. Another disposition of these sundry parts, productive of identical results, is to have 5 and 7c both composed of mixed ignitiblc and detonating substances, on their respective sides of the movable clement le, and to utilize the part 6 on the stationary member 1c as the operating wedge or enlargement.

@ther possible combinations of the same parts will be readily discerned by experts in` the art to which the present invention ap-` pertains.

Fig. X shows how the staple 3d may be employed to hold the movable element ld in position on the stationary member 1d, and also to fasten together the opposite ends, edges, or other lapping portions of this member when rolled upon itself to form a casing for the favor, or the like.` A relatively fixed element is represented as projecting outwardly from a wrapper 10, enveloping the said casing as well as the movable element 4d and other related parts as a whole. The element 40 is secured in position on the side of the casing member 1d by a wire staple 30, which also servesto "fasten together the opposite parts of this casing at the end remote from that where the staple 3d is applied. v

In Fig. XI is depicted another species of casing member le, on which a plurality of movable elements 4E@ can be maintained under each of a series of staples 3,dis`posed peripherally around the external circumference of the said casing, at one end thereof. At the opposite end of the casing member 1 is shown a plurality of similar movableelements 4f each independently held to the side ofthe member le by its own staple 3f. Both series of movable members le and 4f, it will be observed, are provided with their respective dctonating enlargements 7 and 7 f, adapted to be set olf upon being pulled outwardly under or against the corresponding staples 3e and 3f. With this arrangement, it is now obvious that by pulling out the said movable elements 4F and 4f one after another at either end of the stationary member l, a. person `or couple manipulating the same can produce a continuous volley of cracking sounds, well calculated to cause surprise and merriment. 1

Due to the width A tween the legs of the staple 3, Figs. I and II, the movable element l is allowed sufficient freedom of motion to enable it even to be pulled sidewise, and yet the ignitible compound 5 thereon will obtain the required contact and frictional impact with the detonating composition 6 upon the stationary member 1. The same observation applies to the other forms of the invention wherein the movable member is arranged to pass through a. wide staple.

In Figs. V, VI and VII, a seal 8, indicated by do-t-and-dash lines, is shown as eX- tending over the ignitible and detonating constituents. This affords a protective covering, which prevents injury to thesev substances through exposure to -the atmosphere. When thus protected by sealing matter, the device is especially suitable for use as a lowpriced burglar alarm. For such use, the

of space provided be- `member 1b and element 4b can be readily fastened, for instance by means of thumb-tacks,

just one for each,\to the edge of a door and its trim, or to theadjacent upper and lower stiles of a pair of window-sashes.

As shown in the lower half of Fig. XI,

thestaple 3e may continuously encircle, or

ordinary boolcbinders stitch can be rcsorted to, if desired, to attach the igniter, as

well as the detonator, on eitherthe outside or the inside of the relatively fixed member `1. The shape of the latter is rather immaterial, as various `forms thereof besides that shown may be used with equally satisfactory results.

The aforementioned detonator and igniter, to wit, the chemical ingredients pos sessing the physical properties of producing j a distinctly audible sound or loud report and generating or setting off the same, may be inclosed, either individually or combined, in a. cap of approved design, which inturn can be gluedor otherwise aiiXed to the movable element 4, or its equivalent.

A shield 9, of fireproof material, may be superimposed upon the inner end of the movable element 4d, and the juxtaposed ingredients 5, 6d and 7d asrepresented in Fig. X. This will preclude ignition or `combustion ofthe enveloping wrapper 10, which possibly might result from a spark, flash, or

flareup of the fulminate or detonatingsubstance employed. j

It should be noted that the invention is not conned to the precise forms and exact details of construction herein specified and illustrated in the various figures of the drawing hereto annexed, as obviously numerous changes, alterations, and modifica tions can be effected in the same, without departing from the fundamental principles` ofthe invention or sacrificing any of its ,chief advantages. The right, therefore, of

making any or all such changes, alterations and modifications, is entirely reserved.
